Production of a compostable cup

The majority of the compostable products we see in Irish coffee shops are made by utitilising plant-based products such as PLA (Polylactic acid or polylactide). PLA is created by using fermented starch from plants such as corn, sugarcane and sugar beet. The PLA replaces the need for the plastic lining you will find inside regular coffee cups. This material, PLA, is not water-soluble, so it does a good job of containing your flat white.
